Like Tom said sounds like a GP issue, I would check this first.

Here is the Diesel Giant GP troubleshooting info.
Mercedes Diesel Glow Plug Repair

If the problem persists, pump the Primer Pump a few times and if she starts then it could be fuel bleeding off some. with a full tank of fuel, the gravity flow would keep this from happening, maybe a tank below 1/2 this could happen.

Fuel filters would be the next thing to change, and the often over looked tank screen. since this is your summer car and it sits all winter, you could have some bugs growing in the tank. how does the Pre-filter look?


Vacuum is to turn the fuel off and shut the engine down.
However if there is vac applied to the Vacuum shut off valve, then it won`t start.
The brown line at the rear of the Injection pump goes to the vac shut off valve.
